Game slows down - 1/1/2011 11:44:26 PM

Status: offline 		When I start up WitE it is quick and responsive. However, after about half an hour it has slowed down to a crawl and is almost unplayable. I then usually have to reboot to get the speed back up.

I have recently extended my memory to 2 GB which should be enough.

My system specs are

Windows XP Home
Directx 9.0c
AMD Athlon 3200+ 64 bit processor (2.01 GHz speed)
2 GB of RAM
A FX5200 Video card with 128 MB of RAM
16 bit sound card
I have the latest video and sound card drivers

Apart from my video card being light on RAM, though still meeting minimum requirements, the rest of my specs are recommended

Status: offline 		Next time it slows down, press <Ctrl><Alt><Delete>... a box should pop up... use the menu links to see your actual memory resource usage remaining as opposed to how much you start with "free". It could be that you don't have as much freed up unused memory as you might think...OR... WITE might have a memory leak issue requiring occasional save/exit to desktop/reload. In rare cases a reboot might even be necessary.

Does it slow down each time you run it over 0:30 min? What game version you are running?

I have had this problem in all versions; as released, 1.01 beta 1 and I am currently using v1.02 beta 1.

It happens every time

I have included some shots of my task manager. I am no expert but if I am reading it correctly it is showing I have 2 GB of RAM and 600 MB free.

Regards

Marc

Please turn off all other background programs after a clean reboot and see if this continues to happen.

Status: offline 		Hm.. you have huge amount of page faults. Page fault means that physical memory can not be accessed (no available) and virtual memory (disk) is used instead. No wonder it runs very slow.

Does it appear that high when you start the game? If not, can you track when the page faults start growing?

I have Windows XP laptop with 2G RAM, but never seen such memory anomalies.

When I open the game it is on 520K used vs 275 Page faults

When I load Road to Leningrad, I am on turn 9, it jumps to 588K used vs 348 page faults

First time I scroll around it jumped to 605K used vs 450 Page faults

Then any time I do anything, even get a pop up on the map, the page faults relentlessly start to build up. If I don't move the mouse then nothing happens.

I tried ending the turn and running it, but no significant change in memory occurred, used or paged.

When I call up a screen, the production screen for example, paged memory rises, but once the screen is up and I move the mouse around paged memory is stable. It would seem that page faults increase whenever I interact with the GUI, nothing else affects it.

I recently increased memory from 512MB to 2GB. I am obviously accessing more than 512MB now, that can be seen from the task manager shots I posted. I wonder if there are any memory management settings that need adjusting?

I usually play with only WitE running, and my security software.

I have just done a check though and only having WitE has no affect, the problem persists

Status: offline 		One thing which look odd for me the amount of Commit Charge Limit, i.e. total amount of Physical and Virtual memory. It seem that page files ~700MB, which would be a bit too low for 2G RAM. There could be no space to page out inactive processes.

What it is the setting for your virtual memory? My Computer Properties -> Advanced Tab -> Performance settings -> Advance Tab -> Virtual Memory -> Change..

For SWAP file I would suggest:

#1
Make SWAP in its own partition (this is VERY VERY important) and leave enough room for it (2.5x times the RAM at the minimum as recommended my Microsoft)!

#2
If you have 2 HDDs I suggest beginning of 2nd HDD (the Operating System should be at the beginning of 1st HDD).

My virtual memory is set to 768 MB. I have oodles of hard Disk space. Would you suggest increasing VM. For 2 Gb of RAM what would be a reasonable value?

Marc,

As I know (which is different from Leo statement) the minimum page size file should be 1.5xRAM (768 seems to be minimum for your previous memory size - 1.5x512MB). I'd say set it to 3-4G and see if there is any difference. Also, there is an option to let Windows vary the size of page file.

Advises by Leo sound more as a top level fine tuning for the huge SQL server

when I went to "Virtual Memory > Change" it recommended 3070 MB, which is what I specified, with 6000 MB max. However, it seem to have made no difference what so ever. Used and VM Size remain around 600 MB and Page Faults increases relentlessly. I have seen it reach 2,000,000.

Status: offline 		Hi all,

One other thing... this is 32 bit WinXP!

There is limit of how much memory can be addressed here... thus the physical RAM + SWAP should not exceed the 4 GB (3.something to be exact)...

And yes - in old days x1.5 to x2.5 time the RAM was the nrm of SWAP file - now it is still the same with 64 bit OS (for example I have 12 GB RAM Vista 64 bit at work and I have 20 GB dedicated SWAP partition - the SWAP is automatically done by OS and it grows and shrinks - usually it is many many GBs big)...

Status: offline 		OK, I know this is going to sound strange but hear me out.

I finished playing Road to Leningrad and started Road to Kiev. Everything was fine. Nothing slowed down. Page Faults reached 20 million at one point but had no impact on game speed, it was fine. (I am guessing it creates the page faults but doesn't access them.)

So I loaded up Road to Leningrad again. Very slow. Slow scrolling, slow unit selections, slow bringing up reports. Anything to do with the interface. Again, getting progressively slower with time.

So I load up Road to Dnepropetrovsk. This time it is fine, speed OK.

So I decide to load the main campaign (41-45). When I am on the lower half of the map, below the Pripet Marshes speed is fine. When I am on the upper half of the map, above the marshes, very slow. Around Leningrad it takes a second or two before it starts scrolling. And don't even try to call up the production screen, it takes several seconds to come up.

However, if you use the jump map to jump to the Kiev region and press P the production screen comes up almost immediately.

(P.s. I don't play with sound on, I did rename the directory to no sound but it didn't make any appreciable difference)
